The present disclosure relates to transmission methods and devices inwireless communication systems, and in particular to a Sidelink-relatedtransmission scheme and device in wireless communications.

Related Art

Application scenarios of future wireless communication systems arebecoming increasingly diversified, and different application scenarioshave different performance demands on systems. In order to meetdifferent performance requirements of various application scenarios, the3^(rd) Generation Partner Project (3GPP) Radio Access Network (RAN) #72plenary session decided to conduct the study of New Radio (NR), or whatis called fifth Generation (5G). The work Item (WI) of NR was approvedat the 3GPP RAN #75 plenary session to standardize the NR.

In response to rapidly growing Vehicle-to-Everything (V2X) traffic, 3GPPhas started standards setting and research work under the framework ofNR. Currently, 3GPP has completed planning work targeting 5G V2Xrequirements and has included these requirements into standard TS22.886,where 3GPP identifies and defines 4 major Use Case Groups, coveringcases of Vehicles Platooning, supporting Extended Sensors, AdvancedDriving and Remote Driving. At 3GPPRAN #80 Plenary Session, thetechnical Study Item (SI) of NR V2X has already been started.

SUMMARY

In NR V2X system, when confronting scenarios out of coverage, in tunnelsor lacking network signal, the Sidelink (SL) can be utilized forprovision of positioning with wider coverage, less latency and higherprecision. But the difficulty lies in the fact that due to the mobilityof vehicles, it will be hard to find transmitting nodes sharing the samecrystal oscillation, radio frequency and center frequency that can beused for three-point positioning.

To address the above problem, a method for SL positioning is disclosedby the present disclosure to construct a three-point-position scenarioby associating positioning reference signals sent by a samecommunication node in different geographical positions and the movingdistances for notifying the communication node. It should be noted thatthe embodiments of the UE of the present disclosure and thecharacteristics in the embodiments may be applied to a base station ifno conflict is incurred, and vice versa.

FIG. 3 is aschematic diagram illustrating an example of a radio protocolarchitecture of a user plane 350 and a control plane 300. In FIG. 3 ,the radio protocol architecture for a control plane 300 between a firstnode (UE or RSU in V2X, or vehicle-mounted equipment or vehicle-mountedcommunication modules) and a second node (gNB, UE, or RSU in V2X, orvehicle-mounted equipment or vehicle-mounted communication modules), orbetween two UEs is represented by three layers, which are a layer 1, alayer 2 and a layer 3, respectively. The layer 1 (L1) is the lowestlayer which performs signal processing functions of various PHY layers.The L1 is called PHY 301 in the present disclosure. The layer 2 (L2) 305is above the PHY 301, and is in charge of the link between the firstnode and the second node, and between two UEs via the PHY 301. The L2305 comprises a Medium Access Control (MAC) sublayer 302, a Radio LinkControl (RLC) sublayer 303 and a Packet Data Convergence Protocol (PDCP)sublayer 304. All the three sublayers terminate at the second nodes ofthe network side. The PDCP sublayer 304 provides data encryption andintegrity protection, and also provides support for handover of a secondnode between first nodes. The RLC sublayer 303 provides segmentation andreassembling of a packet, retransmission of a lost packet through ARQ,and detection of duplicate packets and protocol errors. The MAC sublayer302 provides mapping between a logical channel and a transport channelas well as multiplexing between logical channels. The MAC sublayer 302is also responsible for allocating between first nodes various radioresources (i.e., resource block) in a cell. The MAC sublayer 302 is alsoin charge of HARQ operation. In the control plane 300, The RRC sublayer306 in the L3 layer is responsible for acquiring radio resources (i.e.,radio bearer) and configuring the lower layer using an RRC signalingbetween the second node and the first node. The radio protocolarchitecture in the user plane 350 comprises the L1 layer and the L2layer. In the user plane 350, the radio protocol architecture used forthe first node and the second node in a PHY layer 351, a PDCP sublayer354 of the L2 layer 355, an RLC sublayer 353 of the L2 layer 355 and aMAC sublayer 352 of the L2 layer 355 is almost the same as the radioprotocol architecture used for corresponding layers and sublayers in thecontrol plane 300, but the PDCP sublayer 354 also provides headercompression used for higher-layer packet to reduce radio transmissionoverhead. The L2 layer 355 in the user plane 350 also comprises aService Data Adaptation Protocol (SDAP) sublayer 356, which is in chargeof the mapping between QoS flows and a Data Radio Bearer (DRB), so as tosupport diversified traffics.

Embodiment 4

Embodiment 4 illustrates a schematic diagram of a first communicationdevice and a second communication device according to the presentdisclosure, as shown in FIG. 4 . FIG. 4 is a block diagram of a firstcommunication device 410 and a second communication device 450 incommunication with each other in an access network.

The first communication device 410 comprises a controller/processor 475,a memory 476, a receiving processor 470, a transmitting processor 416, amulti-antenna receiving processor 472, a multi-antenna transmittingprocessor 471, a transmitter/receiver 418 and an antenna 420.

The second communication device 450 comprises a controller/processor459, a memory 460, a data source 467, a transmitting processor 468, areceiving processor 456, a multi-antenna transmitting processor 457, amulti-antenna receiving processor 458, a transmitter/receiver 454 and anantenna 452.

In a transmission from the first communication device 410 to the secondcommunication device 450, at the first communication device 410, ahigher layer packet from a core network is provided to thecontroller/processor 475. The controller/processor 475 implements thefunctionality of the L2 layer. The controller/processor 475 providesheader compression, encryption, packet segmentation and reordering, andmultiplexing between a logical channel and a transport channel, andradio resource allocation of the second communication device 450 basedon various priorities. The controller/processor 475 is also in charge ofa retransmission of a lost packet and a signaling to the secondcommunication device 450. The transmitting processor 416 and themulti-antenna transmitting processor 471 perform various signalprocessing functions used for the L1 layer (i.e., PHY). The transmittingprocessor 416 performs coding and interleaving so as to ensure a ForwardError Correction (FEC) at the second communication device 450 side andthe mapping to signal clusters corresponding to each modulation scheme(i.e., BPSK, QPSK, M-PSK, and M-QAM, etc.). The multi-antennatransmitting processor 471 performs digital spatial precoding, whichincludes precoding based on codebook and precoding based onnon-codebook, and beamforming processing on encoded and modulatedsignals to generate one or more spatial streams. The transmittingprocessor 416 then maps each spatial stream into a subcarrier. Themapped symbols are multiplexed with a reference signal (i.e., pilotfrequency) in time domain and/or frequency domain, and then they areassembled through Inverse Fast Fourier Transform (IFFT) to generate aphysical channel carrying time-domain multicarrier symbol streams. Afterthat the multi-antenna transmitting processor 471 performs transmissionanalog precoding/beamforming on the time-domain multicarrier symbolstreams. Each transmitter 418 converts a baseband multicarrier symbolstream provided by the multi-antenna transmitting processor 471 into aradio frequency (RF) stream, which is later provided to differentantennas 420.

In a transmission from the first communication device 410 to the secondcommunication device 450, at the second communication device 450, eachreceiver 454 receives a signal via a corresponding antenna 452. Eachreceiver 454 recovers information modulated to the RF carrier, andconverts the radio frequency stream into a baseband multicarrier symbolstream to be provided to the receiving processor 456. The receivingprocessor 456 and the multi-antenna receiving processor 458 performsignal processing functions of the L1 layer. The multi-antenna receivingprocessor 458 performs reception analog precoding/beamforming on abaseband multicarrier symbol stream provided by the receiver 454. Thereceiving processor 456 converts the processed baseband multicarriersymbol stream from time domain into frequency domain using FFT. Infrequency domain, a physical layer data signal and a reference signalare de-multiplexed by the receiving processor 456, wherein the referencesignal is used for channel estimation, while the data signal issubjected to multi-antenna detection in the multi-antenna receivingprocessor 458 to recover any second communication device 450-targetedspatial stream. Symbols on each spatial stream are demodulated andrecovered in the receiving processor 456 to generate a soft decision.Then the receiving processor 456 decodes and de-interleaves the softdecision to recover the higher-layer data and control signal transmittedby the first communication device 410 on the physical channel Next, thehigher-layer data and control signal are provided to thecontroller/processor 459. The controller/processor 459 performsfunctions of the L2 layer. The controller/processor 459 can beassociated with a memory 460 that stores program code and data. Thememory 460 can be called a computer readable medium. In a transmissionbetween the first communication device 410 and the second communicationdevice 450, the controller/processor 459 provides demultiplexing betweena transport channel and a logical channel, packet reassembling,decrypting, header decompression and control signal processing so as torecover a higher-layer packet from the core network. The higher-layerpacket is later provided to all protocol layers above the L2 layer, orvarious control signals can be provided to the L3 layer for processing.

In a transmission from the second communication device 450 to the firstcommunication device 410, at the second communication device 450, thedata source 467 is configured to provide a higher-layer packet to thecontroller/processor 459. The data source 467 represents all protocollayers above the L2 layer. Similar to a transmitting function of thefirst communication device 410 described in the transmission from thefirst communication device 410 to the second communication device 450,the controller/processor 459 performs header compression, encryption,packet segmentation and reordering, and multiplexing between a logicalchannel and a transport channel based on radio resource allocation so asto provide the L2 layer functions used for the user plane and thecontrol plane. The controller/processor 459 is also responsible for aretransmission of a lost packet, and a signaling to the firstcommunication device 410. The transmitting processor 468 performsmodulation and mapping, as well as channel coding, and the multi-antennatransmitting processor 457 performs digital multi-antenna spatialprecoding, including precoding based on codebook and precoding based onnon-codebook, and beamforming. The transmitting processor 468 thenmodulates generated spatial streams into multicarrier/single-carriersymbol streams. The modulated symbol streams, after being subjected toanalog precoding/beamforming in the multi-antenna transmitting processor457, are provided from the transmitter 454 to each antenna 452. Eachtransmitter 454 first converts a baseband symbol stream provided by themulti-antenna transmitting processor 457 into a radio frequency symbolstream, and then provides the radio frequency symbol stream to theantenna 452.

In a transmission from the second communication device 450 to the firstcommunication device 410, the function of the first communication device410 is similar to the receiving function of the second communicationdevice 450 described in the transmission from the first communicationdevice 410 to the second communication device 450. Each receiver 418receives a radio frequency signal via a corresponding antenna 420,converts the received radio frequency signal into a baseband signal, andprovides the baseband signal to the multi-antenna receiving processor472 and the receiving processor 470. The receiving processor 470 and themulti-antenna receiving processor 472 jointly provide functions of theL1 layer. The controller/processor 475 provides functions of the L2layer. The controller/processor 475 can be associated with the memory476 that stores program code and data. The memory 476 can be called acomputer readable medium. In the transmission between the secondcommunication device 450 and the first communication device 410, thecontroller/processor 475 provides de-multiplexing between a transportchannel and a logical channel, packet reassembling, decrypting, headerdecompression, control signal processing so as to recover a higher-layerpacket from the second communication device (UE) 450. The higher-layerpacket coming from the controller/processor 475 may be provided to thecore network.
